i've tried 3 or 4 but i couldn't get any to work right

thanks

Explain it better and I may be able to help you, I normally can as long as I know what you're talking about.

Explained Better: Do you have an actionscript code i can apply to a movieclip to make it rotate, face, and move in 8 directions by using the arrow keys, up to go forward in the direction your facing, right to rotate to the right, left to rotate to the left, and down to go backwards from the direction your facing. Like a spaceship or something.

For example, the spaceship in this game http://addictinggames.com/asteroidsduel.html

Although I'd rather write a post walking you through how to do this, I've never tried flash game programming so I'm not too sure myself but a quick google around got me:

That should contain what you were after.

I don't mean any offence here but you seem pretty new to flash and actionscript, I recommend getting a book or doing beginner tutorials for the basics rather than just copying and pasting code and not fully knowing what all of it does.

Thanks for the site, and about the beginner tutorials thing, I've done most of those. It's moving on to the intermediate tutorials that's the problem lol.

After cutting down the code from that website here's the code for anyone else that wants it. Just create a movieclip and give it an instance name of ship.

Code: Select all

function makeShip (){
   
   ship.angle = 0;    
   ship.xv = 0;       
   ship.x = 0;       
   ship.y = 0;       
   ship.yv = 0;       
   ship.xa = 0;       
   ship.ya = 0;       
   ship.v = 0;       
   ship.visc = 0.02;    
   ship.drag = 0;       
   
   
   mp = Math.PI, mpow = Math.pow, msr = Math.sqrt;
   
   ship.onEnterFrame = function() {
      
      if (Key.isDown(Key.RIGHT)) {
         this.torque = 5;
      } else if (Key.isDown(Key.LEFT)) {
         this.torque = -5;
      } else {
         this.torque = 0;
      }

      this.rtorque = 0.5*this.AngVelocity;
      this.AngAcceleration = this.torque-this.rtorque;
      this.AngVelocity += this.AngAcceleration;
      this.angle += this.AngVelocity;

      if (this.angle<0) {
         this.angle += 360;
      }
      if (this.angle>360) {
         this.angle -= 360;
      }

      this.v = msr(mpow(this.xv, 2)+mpow(this.yv, 2));
      this.drag = this.visc*this.v;

      
      if (Key.isDown(Key.UP)) {
         this.force = 1;
      } else {
         this.force = 0;
      }
      this.xa = ((this.drag*this.xv)*-1)+(this.force*Math.sin(mp/180*this.angle));
      this.ya = ((this.drag*this.yv)*-1)-(this.force*Math.cos(mp/180*this.angle));
      this.xv += this.xa;
      this.yv += this.ya;
      this._y += this.yv;
      this._x += this.xv;
      this._rotation = this.angle;

   };
}

function Game() {
   
   doo = new makeShip();
   
}

foo=new Game();



Apply this to the actionscript on the keyframe, not on the actual mc.
